javac package com.phidget22 does not exist

Post by DarylL »

I am followint the guidelines for compiling my program in java, but keep getting the error message that package com.phidget22 does not exist

- my app, as well as phidgets22.jar are located in the same folder
- When I use the command 'java -classpath .:phidget22.jar Train.java' I get an error message stating " package com.phidget22 does not exist
import com.phidget22.*;"
- When I use the command 'java -classpath .:phidget21.jar Train.java' I get an error message stating " Could not find or load main class Train.java"

here is my code (please note that I have had to replace . in two places with (dot):

Code: Select all

import com.phidget22.*;
import java.util.Scanner; //Required for Text Input
import java(dot)io.IOException;

public class Train{

	public static void main(String[] args) throws Exception {
		VoltageInput voltageInput0 = new VoltageInput();
		DigitalOutput digitalOutput0 = new DigitalOutput();

		voltageInput0.addVoltageChangeListener(new VoltageInputVoltageChangeListener() {
			public void onVoltageChange(VoltageInputVoltageChangeEvent e) {
				channel = digitalOutput0.getChannel();
				if (channel == 0){
					if (str(voltage) < "2.5"){
						if (digitalOutput0.getDutyCycle() == 0);
							digitalOutput0.setDutyCycle(1);
				} else {
//		#					print("voltage: " + str(voltage))
//		#					print("DutyCycle: " + str(digitalOutput0.getDutyCycle()))
							digitalOutput0.setDutyCycle(0);
				}
				}
			}
		});

		voltageInput0.open(5000);
		digitalOutput0.open(5000);

		digitalOutput0.setDutyCycle(1);

		//Wait until Enter has been pressed before exiting
		System(dot)in.read();

		voltageInput0.close();
		digitalOutput0.close();
	}
}

Found my problem... was using the wrong JDK. Thanks to your guides for helping me fix it. :D
